Unfallbericht:
The Yakovlev operated on a training flight during which the pilots were practicing countering a (simulated) uncommanded stabilizer trim change. During these manoeuvres the airplane stalled. It entered a spin and crashed 1.4 km west of Novogupalovka railway station near Kazakovskoye.

Probable Cause:

Conclusion: The cause of the disaster is the loss of airspeed, followed by stall and transfer to a tailspin. Possible causes of speed loss are:
a) a mistake in the piloting technique by the crew;
b) piloting the aircraft according to, possibly, overestimated readings of the left pilot's airspeed indicator.
